You WILL fix what he's pointing out, right?
It frustrates me when people give constructive criticism on a build and the OP pulls the "it's not done!" card and then doesn't even indicate whether or not he will fix the problem. Sorry if I seem angry, but the way you worded that seemed somewhat dismissive of what he was pointing out.
I like the idea you're going for here. Looks like a souped-up gymnastic platform TDM.
However, I would recommend you work more on developing more detailed platforms. Right now they look pretty bland. Try using some ramp and wedge bricks, to give it a more jagged but believable appearance.
I realize the difficulty in creating spherical objects in a lego-based game, but there are better ways to go about making a sphere-shaped sun. That sun right now looks like someone dumped napalm on Jabba the Hutt.
